. The present invention relates to a repeating firearm with bolt action and; case magazine.

Repeating guns with bolt actionsand magazines of different kinds are known per 5 se. The hitherto known arrangements are however not well suitedfor cartridges with projecting rims. When cartridges of this type are use, the same must be so. positioned in the case magazine, that the rim of each cartridge lies in front of the rim' of the next underlying cartridge, since the loading action will be disturbed if the rim of a cartridge lies behind the rim of the underlying in repeating guns with case magazines.

Several types of cartridges can how,ever, on account of the small diameter of the bottom of the cartridge shell or from other causes only be manufactured with projecting rims. Lately the use of such cartridges has increased steadily and the invention is particularly adapted for use in connection with cartridges of this kind, but the novel arrangement may also with advantage be utilized in connection with cartridges of other forms.

In repeating firearms with case magazines it is of great importace that the magazineis located in such a manner that the lips of the same lie on as high a level as possible and the magazine'lies near the axis of the bore in the barrel. This high position of the magazine prevents that the cartridges have a too great inclination when they are introduced into the barrel and therefore disturbances of the loading action are prevented. Moreover, when the magazine lips are located on a high level a better impact with the front face of the bolt or feeding member is secured, since a larger part of the bottom area of the ascending cartridge comes into contact with the front face of the bolt.

The higher mounting of the magazine, the

5 lips of which project into the bore for the bolt, is however not possible without structural changes,- since the bolt would have to be equipped with longitudinal grooves, which in combination with the magazine lips would prevent the necessary rotating movement when the bolt is locked.

.7 According the present invention the higher mounting of the. magazine lips is made possible by arranging on the front part of the bolt, (which for this purpose has a smaller able sleeve, which does not partake in the rotation of the bolt. It is known per se to use rotatable rings, bolt heads and the like as carriers for the extractor and other parts of the mechanisms. According to the present invention the rotatable sleeve is of greater length than the magazine and the magazine lips. The sleeve is" further formed with longitudinal grooves adapted to receivethe of a corresponding length.

It is also very important, particularly at cartridges with projecting rims, that the lips in points which are-situated as near the 5 ends of the cartridges as possible. For this purpose and in orderto ensure that'the cartridges when repeating will leave the magazine unobstructed, the magazine lips are ac- 7 cording to theinvention' subdivided or inter-' rupted in'longitudinal direction. The rear lip elements are hereby rigidly connected to the magazine, whereas the front lip elementsflare yieldingly movablein'lat- 8 eral direction.

In order that the magazine may be rapid ly and easily filled in correct manner, the 7 magazine is connected to the gun 1n such a manner that it may be swung out about a pivotal point in the rear-part of the same into a position in which it lies fully unobstructed. i Hereby the magazine is arranged in such a manner that the gun must be heldin correct position, i. e. with the muzzle pointing upward or outward, when the cartridges are -Hitherto the front end of the locking bolt high mounted magazine'lips, which also: are 7 carried the locking lugs, which cooperated w th; corresponding grooves in the front part of the receiver, but this arrangement can not i be employed in guns according to the present] invention, since the rotatable sleeve is ar ranged on the front-end of the bolt. The

r elder arrangement also lnvolves considerable Figs. 6 and 7 are cross-sections taken on the lines VIVI and VII- VII of Fig. 5. Fig. 8 is a partially sectioned fragmentary elevation showing a locked gun and the maga- 1 thereby being guided in the longitudinal grooves 15. In the locked position shown in Fig. the slot 16 in the bolt 14 allows the usual rotating movement at which the corresponding support faces of the locking lugs and the bolt 17 are brought into such mutual relation that the device is locked. In Figs. 1 and 8 13b denoted the positions taken up by the locking lugs. lhe bolt sleeve 18 is arranged in such a manner on the thinner fore part of the bolt 14 that it may be rotated on the same. The sleeve 18 is formed with longitudinal grooves 19 into which the magazine lips 20. 20a project and the bolt 14 with the sleeve 18 may therefore be moved length ii rizo'ntal se ctionalyiewsho Ing the central part of the lock.

The magazine case 35 is held in position by a locking pin 38 which catches into an aperture 39, the parallel ribs 36, 37 of the case hereby projecting into corresponding slots in the members 29 and 30. 'The cartridge feeding device 40 with the spring 41 is hereby fixed to the magazine bottom 28 in the usual I manner.

When the locking pin 32 is pressed forward the magazine will turn'on its pivot 31 under the influence of the spring 42 and take up the position shown in Fig. 10. When in this position the magazine can be inspected with ease during the loading operation and a false placing of cartridges with projecting rims is prevented. If nevertheless a cartridge should get into a false position the magazine case 35 can be opened by a single manipulation (Fig. 10) whereby the cartridges 26 will drop out of the magazine, so that the latter is discharged. The emptying of the gun after use is also a very simple opera- 1 tion.
